Mercedes Concept IAA shows its mighty morphing aero aids

Modern supercars are utilizing more active aerodynamic elements that constantly adjust, to make them some of the fastest things on the road. The Mercedes-Benz Concept Intelligent Aerodynamic Automobile is using them too, but the know-how is applied here for ultimate efficiency rather than turning better lap times. In the standard design mode, the four-door luxury coupe looks like a CLS from the near future with styling that's mixed with a little of the F 015 concept. However at the press of a button or upon hitting about 50 miles per hour, the IAA transforms into aero mode to have an insanely low drag coefficent of just 0.19. To achieve the ultra-efficient shape, the rear of the concept stretches over 15 inches to guide air down the tail. Flaps in the bumpers also extend outward, and the wheels adjust to improve the flow around the sides. To trim things out underneath, a portion inside the front bumper moves, as well. Inside, passengers sit in organically shaped leather seats, but occupants have to look at a vast array of purple and blue LED accent lights. The big panoramic roof is a nice touch, though. It would be interesting to watch water tumble over this slippery shape when driving in the rain. To maximize efficiency, Mercedes powers the IAA with a plug-in hybrid that's hooked up to a gasoline engine. The result is 275 horsepower and an electronically limited top speed of 155 miles per hour. On the European testing cycle, the company figures the concept could cover 41 miles solely on electric power in aero mode. Showing the gains of the swoopy transformation, that figure falls to 38.5 miles in design mode.

Luxury car brands scrambling to avoid a blue Christmas

DETROIT — When financial markets surge to new records, sales of luxury cars usually rise, too. Instead, October U.S. auto sales reports on Wednesday showed that a collapse in sales of luxury sedans is accelerating. Consumers have gradually shifted over to luxury sport utility vehicles from sedans in the past decade, but the trend — which has occurred in both the non-luxury and luxury sedan segments of the auto market — was particularly pronounced in October. Sales of Daimler AG's Mercedes-Benz S-Class, long a global benchmark for large, premium sedans, plunged 49 percent in October, and are down 24.8 percent for the year to date. General Motors' Cadillac brand said it sold just 779 of its CTS sedans in October. Demand for that car, designed to compete with German luxury sedans, is down nearly 33 percent for the year. "There's still a significant portion of the market that wants a car, but I'm sure there were people who preferred a horse to a car at one point." Cadillac's best-selling model this year is the XT5 compact SUV, which has more than doubled sales from a year ago. The shift within the luxury vehicle market away from sedans toward SUVs of all sizes is forcing some of the most prestigious brands to scramble to add SUV models to their lineups or boost SUV production to meet demand. "In the short term, there will be pressure to add (consumer) incentives, cut production or both," said Cox Automotive analyst Michelle Krebs. "And we just don't see an end in sight to this trend." The Dow Jones Industrial Average has been trading at all-time highs, usually a good sign for luxury sedans, but as major automakers reported new U.S. vehicle sales for October on Wednesday, sales for passenger cars continued their slide while luxury SUV and crossover sales rose again. According to Kelley Blue Book data, in 2007 luxury sedans made up 7.6 percent of U.S. new vehicle sales, while luxury SUVs made up 4.2 percent. Through September this year, luxury SUVs made up just over 7 percent of the market, compared with 4.9 percent for luxury sedans. In the short term, luxury brands could use holiday season sales promotions to clear slow-selling sedans off dealer lots, analysts said. Toyota's Lexus brand said on Wednesday it will launch its "December to Remember" year-end sales promotion for the 18th straight year.

Hybrids to slowly replace diesels at Mercedes

German automakers have had some success bringing diesel-powered vehicles in America in recent years, but that may not last much longer. A product planner from Mercedes-Benz we spoke to in Austria apparently believes hybrid setups may be more favorable in the long run, and electrified hybrids will eventually replace oil burners. That's why most every concept car we've seen in the last few years features some sort of hybrid or plug-in hybrid setup while there have been very few diesels. "Yes, diesel is technically complex, and very expensive. The additives to reduce particulate matter are very costly. You'll see more hybrids to meet the changing regulations," according to our source. We've seen this exact scenario play out with Mazda, which has struggled to bring its 2.2-liter diesel engine to America, citing the costly process to reduce emissions in order to meet California-level standards while still maintaining suitable performance for the US market. It's certainly interesting that this news comes hot on the heels of revelations that VW, the automaker that offers the most diesel-powered models in the US, was found in violation of emissions rules on its popular 2.0-liter TDI engine. New Mercedes GLE Will Have An Active Chassis Mercedes has launched an all-out product offensive in the last two years, but the product planning think tanks in Stuttgart have a few surprises in store, too. While Benz has just launched its new GLE SUV family, GLE product planners are already hard at work on the next-generation – yes, a good 5-6 years away – and tell us it will evolve to boast new chassis technology, "something that doesn't exist today." The next-GLE is codenamed 167 – the previous ML (now replaced by the GLE) was internally referred to as 166 – and the GLE planner we recently talked to calls the platform an "active chassis." He further alluded that the next version could be electrified. Currently, the only aspect of the GLE's chassis that is 'active' today are the hydraulic pumps on the roll bars, he said. Many of Mercedes' models can already be had with an adaptive air suspension, multiple selectable driving modes, and other features that were rare or nonexistent just a couple generations ago. One More Compact Crossover On The Way The planner said we can also at least one more all-new, forthcoming compact crossover to be built on the GLA platform. In addition to the GLA, that architecture is currently shared by the A-Class, B-Class, and CLA-Class models.
